Referring first to Figs. l.4',' inclusive, we have shown a portion of 'a. rectangular tubular member 2 0 to which the yarn tubes 21 are secured in. the usual manner. The upperand/lower walls of the tubular member,20 are cut away at'each end' to form side projections-22- and recessed portions 23,

A supporting plate orbracket 24 isformed at its upper end in accordance with the usual practice and provides a, spool bear-ing25 and an outer or chain-engaging portion 26 which cooperates with aspring 27 "in attaching the tube'frame to a transporting pattern chain.

The bracket 24 is pnovidedwith notches 28 on'each side thereof, adapted to receive the projections 2 2;ofethe tuhularmember 20 when the parts are assembled, with the brackets or plates, 24 abutting the end surfaces; of the recessedpontions 23* of'said ineinben, After the parts are thus assembled, the projections 22 are bent inward around'the plate or bracket 24 as clearly 1 shown in Fig. 4, embracing. the plate and holding itfirmly againstthe end of the member 20. l

The spring '27 may be secured against the outer face of the projections-22b3 one or more screws 29 threaded into the bracket 24, The spring projects through a slot 30 in the brack t and is thu held r m l r d sp acement It. will. b evident that the brackets 24 are permanently secured to the ends of the: ubular member 20 by the coaction. of. integr l pa o he. bu mm? A second or supporting plate 4:0 is de tachably secured to the attaching plate 35 in any convenient manner as by screws l1.

The plate 10 is also notched or recessed as shown at 412 in Fig. 15 and fits between the ends of the bent projections 37. The usual spring 43 is secured to the outside of the supporting plate lOby screws 14L- and extends upward through a slot 15 in the supporting plate 40. The upper end 01 the attaching plate commonly extended to provide a bearing 46 for the yarn spool 47.

"With this construction, the attaching plate 35 is permanently secured to the end of the member 36 and the supporting plate l0 and spring 4-3 are detachably secured to the plate 35, so that they may be easily removed for repair or replacement. It may benoted that the attaching plate 35 and spool bearing 46 are very rarely injured and practically never require replacement.

In. the .form of our invention shown in Figs. 9&3, each end of the tubular mem- ,ber 50 is provided with two sets ofprojections 51 and 52. Theattaching plate 53 is F oii set or displaced inwardly at 5 1 between the points where it engages the edges of the top an d bottom of the member 50. The plate 53 is also recessed or notched at its opposite edges as shown at 55 in Fig. 16, and fits be-.

tween the projections 51 and 52.

The projections 52 extend outward past the outer surface of the plate 53- and con stitute guides "for positioning the outer or supporting plate '56, while the projections 51 are bent around thedisplaccd portion 5 1 of the plate 53 and hold the plate firmly in position against the end of the tubular member. t V

The supporting plate, 56 is secured to the outer face of the plate 53 by screws, 57, as in the previous form, and is prevented from either lateral or longitudinal displacement by the ears or pro ections 52. A supporting spring 58 is clamped between the outer faces of the embracing projections 51 and the inner face of the-plate 56 and projects up wardly through an elongated slot 59, cross ing the slot both at its upper and lower ends. With this construction the spring can be bent backward flat a gainst the attaching plate 53 if necessary, thus allordingim creased space for movementduring attachmentv to the transporting chain;

Having thus described three forms of our improved bracket and tube 'lrame construc- .tions on the member around a portion of the bracket. The parts are all preferably formed of steel and are well adapted to withstand "the rough usage to which they are at times sub ected.

Having thus described our invention and the advantages thereof, we do not wish to bc'liniitcd to the details herein disclosed otherwise than as set forth in the claims, but what we claim is:

1. A tube frame for looms comprising a' tubular member and supportingbracl'rets for said member, each bracket including a rigid spool bearing plate havingfnotohes in its side edges 'and'said' tubular member having holding portionsco-operating directly with the notched edges ot'said'plate to secure said plate firmly and permanently against the end of said member and from displacement longitudinally of said plate, said holding per tions jand notches forming the entire securing means for said plate. 7

.2. A tube 'itralne'for looms comprising a tubular member and supporting brackets for said member, each bracket including a spool bearing plate abutting portionsof an end of said tubular member on a plurality of'faces thereotand being embraced and 'held in position by theremaining portions of theend of said tubular member, said plate and tubu lla1' member having co-operating portions preventing relative displacement longitudinally of said plate.

A. tube frame for looms, comprising a tubular member andsupporting brackets for said member, each bracketincluding a spool bearing plate lying flat against the ends of the upper and lower walls of said tubular' member and portions of the side walls thereof, and having notches in its side edges receiving outwardly projecting portions 01 said side walls, said projecting portions being bent to embrace a portion of said bracket and to prevent displacement thereof.

4. A tube frame tor-looms comprising a tubular member and su porting brackets for said member, each br'acliet comprising an at taching plate permanently secured in position at an end of the tubular. member, a sup porting plate detachably secured to said attaching plate, and aspring'clamped in position between said attaching and support ing plates. j p

5. A tube frame for looms comprising a tubular member and supporting brackets for said member, each bracket comprising a spool bearing plate having notches in its side edges, and a supporting plate detachably secured thereto, said tubular member having integral projecting portions extending through said notches and bent inWard to partially embrace and hold said spool-bearing plate in fixed position.

6. A tube frame for looms comprising a tubular member and supporting brackets for said member, each bracket comprising an attaching plate abutting one end of said member and having a portion displaced inwardly of said member, means engaging said displaced portion to permanently secure said plate to said member, a supporting plate detachably secured to said attaching plate, and a spring clamped between said supporting plate and the securing means for said attach- ,15 ing plate.

7. A tube frame for looms comprising a tubular member and supporting brackets for said member, each bracket comprising an attaching plate secured to an end of said member, a supporting plate detachably secured to said attaching plate, and a spring clamped between said plates, and extending upwardly through an elongated slot in said supporting plate, said spring crossing said slot in reverse directions near the upper and lower ends of said slot.

In testimony whereof We have hereunto afiixed our signatures.
